[Q] Camera not working (shows only black screen) - G2 and Desire Z Q&A, Help & Troubleshooting

Hey guys,
I've bought Desire Z recently and today a problem occured: when I start the camera app (either via SW shortcut or HW key) I get just backlit black screen and all I can do is to press Home.
Does anyone know a solution?
Thanks.

You're using the stock ROM, right ?
I would try a factory reset. If that doesn't fix the problem, then it sounds like it has a faulty camera, return it.

Yes, I'm using stock ROM. I've tried factory reset for 2 times and it didn't help, so I guess returning the phone is my only option.
The wierd thing is that the camera worked just fine and then it started to show only a black screen.

Move your finger???

Tried, not helping

Now when I think about it I come to conclusion that the problem occured after the last update (the one supposed to enhace camera performance). Could it be the cause? Can it be undone?
If I perform factory reset I still have this update installed (OS version 2.2.1).

Do you still have S-OFF or are you back to S-ON now ? If you are S-ON then there is no way currently for you to downgrade if you're on the new 1.72 ROM, since right now it is not rootable.

I haven't had S-OFF so I don't have now as well.
But it doesn't matter to me anymore, I'm returning the device (already have bought a new one - so far didn't update to the 1.72 ROM and camera works fine). Now I don't know if I should perform the update.
Anyway, thx everybody for trying to help.

[Q] Please help!!! MIC is breaked after Update...

Hi ll,
I really out of ideas here .
I was running Pays 1.9 Bravesoul ROM without any issues for about 4 months on my unbranded Desire(HBOOT 0.75)!
Today I decided to update to Froyo.
I used Rom Manager to upgrade to OpenDesire 3.03 and Radio 32.43.00.32U_5.09.00.20.
Every thing went well, except that I noticed that the MIC doesn't work at all.
Not when I make or receive a call, Not if I try to Mute/Unmute it, Not if i try to Record sound, or Video or WHATEVER!!! The only way the other side can hear me is trough my BT headset.
So I tried to use the LeeDroid 1.7a ROM but same result. Also tried to use different Radio - 32.42.00.32U_5.09.00.08.
I then Nandroid restore to my 1.9 Pays rom (Wiping Data+Cach+ext), but still doesn't work. I tried different Radios:
32.37.00.32U_4.06.00.16_2
32.36.00.28U_4.06.00.02_2
32.26.00.24U_4.04.00.03_2
same thing...
I finally Unrooed my Desire to v1.15.4 Radio 32.30.00.28U_4.05.00.11 without any luck!
So I'm pretty hopeless Please if someone also have / had this issue, Please share!
Thanks!
sounds to me like it's broken mate
i know it's coincidence that it broke as you changed ROM but if it doesn't work on anything there's no explanation
have you tried a hard reset + clearing caches?
if you have then unroot your phone, put it back to your original RUU for warranty purposes and sent it back for repair
by what do you mean Hard Reset?
I wiped all data, I've changed roms.
Currently It's unrooted...
Is it possible for the Radio update to do this? (all the updates went without a hitch)
Or maybe the OpenDesire ROM (I see that v3.03 is removed, do you know why?) did this?
There is no way it a coincidence. I making phone calls all the time, The update took me about 15 min, after which I tried the Video camera and noticed there was no sound...
Thanks!
well, I noticed that the mic works, but extremely week! I really need to shout in order to hear a whisper... I do this in recording...
I'm starting to believe that maybe it's the mimbrein (Or the piezzo) that is ruined inside the mic...
Is it possible to control the gain in software? (Is there still a chance that the S.W upgrade caused this?)

Signal problems after update

Hello all,
I just received my shiny new HOX yesterday and it was working very well at first, however last night I updated it to the latest firmware (with Sense 4.1) and now it will not connect to the mobile network at all (no bars, won't find any networks when I manually search). I have noticed that it seems to be stuck in airplane mode.
Under airplane mode in the settings page it says "off", then a few seconds later it will say "turning off...", then it will go back to saying "off" and then back to "turning off.." and so on. I think it must be a bug in the firmware because I have tested the sim card in another phone (worked fine), and it was working fine before the update.
The only way to see if it is a bug in the firmware (as far as I am aware) would be to install a different ROM. However, I cannot find any way to install a new ROM (custom or stock) without unlocking the bootloader and therefore voiding the warranty (which I don't want to do in case it turns out to be a hardware issue).
I should also add that I could return the phone, but I would like to leave that as a last resort because I live in the middle of nowhere and trying to post stuff if a pain in the ass (and expensive).
I have also tried both a hard and soft reset, with no luck.
This is my first HTC device so I don't really know what I'm doing (although I have plenty of experience rooting and flashing my S2)
Any suggestions would be greatly appreciated
same prob
i've the same problem since the last update. hope it will fixed soon.

I'm glad I'm not the person having this problem . Does anyone know if it is definitely a firmware issue? (I might feel more confident about flashing a custom ROM if that's definitely the problem)
Anybody?
Maybe something went wrong with the OTA flash?
First thing HTC will do is flash the RUU to ensure it's back to stock. It will delete all your data, but it's worth a go.
You can use adb backup.

auto rotate gyroscope sensors not working

Hi, I recently flashed a jellybean in Rom on my HTC one x and the rotation stopped working. So then I decided to return to factory settings with an ruu. So I did that and it was functioning again. So I reinstalled jb still worked.I then decided to try the 4.2 camera on my one x and it stoped working again, I then tried the ruu but this time it did not work. Next day I go home from class decide to unlock and relock the bootloader and it worked again, I then tried to install a in Rom ( once again) but this time it did not work. So I tried the ruu again, didn't work, tried unlock and relock bootloader, factory reset, wipe cache, everything and yes screen rotation is on. I alsotried the app android sensor and it showed my accelerometer/gyro not working. Can someone explain how to fix because its hard for me to believe that its hardware since it happens after I install a Rom or flash something. Please help.

That can happen from time to time with gyros. Even if you get it to work with the right RUU, then you reset the device, it might stop functioning again. I'd say your motherboard needs to be replaced. You can always try with different ROMs and stuff but my thought: your HW is problematic

don't think so, every person who encountered errors like this were on cm10 and its kernel ncx, theres should be something wrong with those things... or people don't flash it correctly
I have this problem as well, but I'm using ARHD rom, right now.
Although I also think it's more a hardware fault, I'm not really 100% sure about it.
Sometimes a new Rom flash or a reset can fix it.
But after a few reboot it gets stuck again :-/
So confused about this problem too
Although, my phone is unlocked now and got Hboot 1.33. I'm gonna wait till the official RUU is out and reset my phone fully (with locked bootloaders) before sending it to HTC for repair.
Maybe you should do that too
I had this problem too. It was fixed for a while after I flashed stock rug but then I clashed another recovery and wham they got knocked out again. Then I installed viper, cm 9 still not working. Installed latest paranoid android 2.53 and they are working again oh and I have latest twrp recovery installed. I really can't say if it is hardware or software. Maybe a mixture of both. I dunno. Only just flashes pa this morning but I have rebooted and they still work. Usually it will get knocked out if I reboot so I'll see what they are doing after a week or so. I'll probably keep pa on here until my official j b OTa is released. I think it did have something to do with either that ncx kernel or a recovery I tried. As that what knocked them out each time. Good luck in fixing it as different people gave had different things that fix the problem. For me it was reverting back to stock ruu. It was 4.03. 1.29..... something. But it also was fixed when I flashed latest paranoid android. Just a fee things to try....

the thing is as I finished everything and had the ARHD V21 I noticed there's problem with my camera !
the problem is sometimes it can get into camera right away without any issues and sometimes it a bit stucks and even force close with messege unable to start the camera and sometimes it force closed without an Error at all !
but when I switch to front camera it shows me Fofocim and then turns purple with lines ahead
I tried another camera app called MXCamera and factory reset and restore backup still problem exist !
so I decided to back to completely stock rom so I relock bootloader and flash custom rom and then run the RUU for my version

Camera won't focus after downgrade to LP

Hey guys,
I got my G4 H815 delivered with MM pre-installed a few months ago. I decided to downgrade to LP to root the phone without unlocking the bootloader. Everything worked like a charm, except the Camera won't focus anymore at all (no matter what app), the manual focus does not work either. I already did multiple factory resets (removed root, tried a different LP version) and cleared the cache for the camera app.
So after nothing worked and I worried my camera got a hardware defect, I returned to Marshmallow, and yes, the focus works perfectly fine once again. So the hardware does work. After that I tried an older LP Update, but same result. So I flashed MM for the second time tonight, and ofc it works on MM...
However, I would prefer to have a rooted (but locked) phone. Is there anything you guys could think of that causes that behavior? As I said, I got my H815 with MM pre installed!
Thanks for your help!
Any ideas?
DO factory reset ! hard reset !

hi !
-the firmware update is to fix errors and improve the phone a bit. there are several videos on youtube that show the focus problem of g4. focus is slow. mine was with MM too so i don't have any personal experience on that problem.
-yes you can root without unlocking. unlocking the bootloader is something you are gonna do to install a custom bootloader or custom recovery.
Also search better this forum. there are custom roms you can install and keep your bootloader untouched
Sorry for bringing up such an old thread, but have you found any fixes? Im having the exact same problem right now.
Same here, I was forced to go back to MM as a result, but i miss having root so much
